X-RAY IMAGING SYSTEM ALLOWING THE CORRECTION OF THE SCATTER RADIATION AND PRECISE DETECTION OF THE DISTANCE BETWEEN THE SOURCE AND THE DETECTOR

摘要

The invention relates to an X-ray imaging system wherein images are obtained using an X-ray blocking element, the system comprising means for determining a position of the detector (40) on the basis of coordinates of projected patterns of the blocker (20, 220) in an image in order to especially be able to perform a calibration and/or correct the contribution of the scatter radiation in a radiographic image obtained by the system.
